Abstract
Ketones and/or carboxylic acids are prepared by reacting, at elevated pressure and temperature and in the absence of a halide, a hydrocarbon containing olefinic unsaturation, particularly aliphatic olefines, with carbon monoxide in the presence of an aqueous solution of a sulphate of an element of Group 8 of the Periodic System, which solution may further contain a salt of a Group 2 element. The process is preferably operated in the temperature range 100-220 DEG C., particularly 190-200 DEG C., and at pressures in the range 150-1000 kg./sq. cm., particularly 200-250 kg./sq. cm., the reaction time being about ten times that for the catalytic addition of water-gas to olefines. In addition to ketones and carboxylic acids, small amounts of aldehydes, alcohols and esters are formed as byproducts together with carbon dioxide. In an example, ethylene is passed under pressure (48 atmospheres) into an autoclave containing toluene and an aqueous solution of ferrous, cobaltous and magnesium sulphates, carbon monoxide is then admitted (88 atmospheres) and mixture autoclaved at 192 DEG C., cooled, more CO admitted (138 atmospheres) and then autoclaved at 197 DEG C., yielding a mixture of diethyl ketone, propionic acid, and small quantities of propyl propionate, n-propanol and propionaldehyde.
